Super-enhancer lncRNA (SE-lncRNAs) are a special set of long noncoding RNAs transcribed from super-enhancer genomic loci. SE-lncRNAs play fundamental roles coupled to the active super-enhancers to regulate the gene expression programs that determine the cell lineages and identities. SE-lncRNA have been associated with many human diseases and their expression manifests in profound phenotypic changes [1-3]. Arraystar has developed the first commercially available SE-lncRNA Arrays for human, mouse, and rat to comprehensively, systematically and sensitively profile the SE-lncRNAs and their cis- or trans-regulated coding genes on the same array. The microarray profiling service is provided from RNA sample to analyzed data. The SE-lncRNA profiling is essential to study the super-enhancer activities, mechanisms, functions and diseases.

SE-lncRNAs sources • Gold standard lncRNAs and reliable lncRNAs from Arraystar Premium transcriptome databases are mapped to the super-enhancer loci catalogued in the dbSUPER database. The lncRNAs overlapped with the super-enhancers are identified and annotated as SE-lncRNAs.
• Enhancer-lncRNAs from literature [4, 5], whose genomic loci overlap with the cataloged super-enhancer loci.
Super-lncRNAs sources Super-lncRNAs are long noncoding RNAs which form RNA:DNA:DNA triplex with multiple anchor DNA sites within the super-enhancers and recruit regulators to the super-enhancers. Super-lncRNAs influence chromatin organization and act as spatial amplifiers for key tissue-specific genes associated with super-enhancers[6].
SE-lncRNA targeted coding genes sources The Refseq genes that either overlap with the SE-lncRNA genomic loci or whose transcription start sites (TSS) fall within 50 kb of the SE-lncRNA genomic loci boundaries are collected as SE-lncRNA targeted coding genes. These genes include 3153 transcription factors (TFs) from TF checkpoint database and 1448 cancer genes from Bushman Lab database.
